hi, I am a new user of libvirt ,i really appreciate libvirt，and want to use it in my work.I want to use it to conncet to a ESXi server.when I try to connect to the server ,I use the command :virsh -c esx://name@exmaple.com,And I get an

1.error :error: internal error curl_easy_perform() returned an error: Couldn't connect to server (7) : couldn't connect to host  so I think maybe the firewall shutdown the 443 for https,so I used command:virsh -c esx://name@example.com/?transport=http And I still get an error like: error: internal error HTTP response code 417 for call to 'RetrieveServiceContent' error: failed to connect to the hypervisor

HTTP error code 417 is related to the Expect header. The error indicates that the server or a proxy in between doesn't handle the Expect header. I assume that the ESXi sever itself is not the problem, because it works for me here. Maybe there is a HTTP proxy between your computer and the ESXi server that returns this 417 error code. This problem is probably related to libvirt sending a dummy Expect header instead of sending no Expect at all. If you're building libvirt from source you can try this patch that I just send to the mailing list for review https://www.redhat.com/archives/libvir-list/2012-February/msg00860.html It fixes the Expect header problem and might fix your connection problem. -- Matthias Bolte http://photron.blogspot.com
